前提
入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。

准备工作
表格控件将拆分为2部分，1：行元素控件，2：列表控件
为了具有更好的扩展性，更加的open，使用接口对行元素进行约束，当行样式或功能不满足你的需求的时候，可以自定义一个行元素，实现接口控件，然后将类型指定给列表控件即可
表格控件用到了分页控件，如果你还没有对分页控件进行了解，请移步查看
（十二）c#winform自定义控件-分页控件
开始
定义一些辅助东西
1 public class datagridviewcellentity
2 {
3 public string title { get; set; }
4 public int width { get; set; }
5 public system.windows.forms.sizetype widthtype { get; set; }
6
7 }
1 public class datagridvieweventargs : eventargs
2 {
3 public control cellcontrol { get; set; }
4 public int cellindex { get; set; }
5 public int rowindex { get; set; }
6
7
8 }
1 [serializable] 2 [comvisible(true)] 3 public delegate void datagridvieweventhandler(object sender, datagridvieweventargs e);
1 public class datagridviewcolumnentity
2 {
3 public string headtext { get; set; }
4 public int width { get; set; }
5 public system.windows.forms.sizetype widthtype { get; set; }
6 public string datafield { get; set; }
7 public func<object, string> format { get; set; }
8 }
定义行接口

32 void reloadcells();

36 /// <param name="intindex">cell下标</param>
37 /// <returns>返回true则表示已处理过，否则将进行默认绑定（通常只针对有text值的控件）</returns>
38 void bindingcelldata();
39 /// <summary>
40 /// 设置选中状态，通常为设置颜色即可
41 /// </summary>
42 /// <param name="blnselected">是否选中</param>
43 void setselect(bool blnselected);
44 }
创建行控件
添加一个用户控件，命名ucdatagridviewrow，实现接口idatagridviewrow

如果你仔细看，你会发现行我用了类型进行传入，当你需要更丰富的行内容的时候，可以自定义行控件，然后通过rowtype属性传入
分页控件我使用了分页控件基类ucpagercontrolbase，这样做的好处就是你同样可以扩展分页控件
用处及效果
调用示例
1 list<datagridviewcolumnentity> lstculumns = new list<datagridviewcolumnentity>();
2 lstculumns.add(new datagridviewcolumnentity() { datafield = "id", headtext = "编号", width = 70, widthtype = sizetype.absolute });
3 lstculumns.add(new datagridviewcolumnentity() { datafield = "name", headtext = "姓名", width = 50, widthtype = sizetype.percent });
4 lstculumns.add(new datagridviewcolumnentity() { datafield = "age", headtext = "年龄", width = 50, widthtype = sizetype.percent });
5 lstculumns.add(new datagridviewcolumnentity() { datafield = "birthday", headtext = "生日", width = 50, widthtype = sizetype.percent, format = (a) => { return ((datetime)a).tostring("yyyy-mm-dd"); } });
6 lstculumns.add(new datagridviewcolumnentity() { datafield = "sex", headtext = "性别", width = 50, widthtype = sizetype.percent, format = (a) => { return ((int)a) == 0 ? "女" : "男"; } });
7 this.ucdatagridview1.columns = lstculumns;
8 this.ucdatagridview1.isshowcheckbox = true;
9 list<object> lstsource = new list<object>();
10 for (int i = 0; i < 200; i++)
11 {
12 testmodel model = new testmodel()
13 {
14 id = i.tostring(),
15 age = 3 * i,
16 name = "姓名——" + i,
17 birthday = datetime.now.addyears(-10),
18 sex = i % 2
19 };
20 lstsource.add(model);
21 }
22
23 var page = new ucpagercontrol2();
24 page.datasource = lstsource;
25 this.ucdatagridview1.page = page;
26 this.ucdatagridview1.first();
如果使用分页控件，则将数据源指定给分页控件，否则直接指定给表格控件数据源
